Neptune 1 rocket online.

― PDA, Dialogue


The Neptune Escape Rocket is a vehicle that is used to leave Planet 4546B. It consists of five constructable parts: the Neptune Launch Platform, the Neptune Gantry, Neptune Ion Boosters, Neptune Fuel Reserve, and Neptune Cockpit. The Neptune Launch Platform can be built using the Mobile Vehicle Bay, while the other four components are built on the launch platform. The player can enter it after the Gantry, Boosters, and Fuel reserve is built.

The Neptune Escape Rocket cannot be launched unless the Quarantine Enforcement Platform is disabled. Attempting to do so will result in the PDA informing the player that the base needs to be disabled.


The Neptune is a ion powered rocket used to leave Planet 4546B after the Quarantine Enforcement Platform is disabled. Once the launch procedure is completed the final cut-scene begins and the game comes to an end.


The Player can find the blueprints for the Neptune Launch Platform inside the Captain's Quarters of the Aurora. The door will be locked, but can be accessed using the entry code, which is 2679. Accessing the data entry will unlock the Blueprints. The ingredients for all Neptune systems are not accessible right after acquiring it, instead the ingredients of each system are revealed after the previous system is constructed.

The Neptune Launch Platform is a very large floating barge with ladders on each side. In the middle is a circular indentation where the rocket will sit. On one side is a terminal used to construct the individual rocket segments, and can be used to rename and recolor the rocket once it has been fully completed. The terminal possesses fabrication drones similar to the Mobile Vehicle Bay.

The Neptune Gantry is the second component of the Neptune Rocket. It consists of a small metal pillar with a bridge (which eventually leads into the Neptune Rocket) and an elevator which can lift the player to the top of the gantry to access the cockpit.

Neptune Stage 2.png

The first stage of the Neptune Rocket consists of a cylindrical shape with launching clamps connected to it. This portion consists of the thrusters which will provide enough velocity to leave the orbit, and serves no personal function other than to progress to the other stage.

The second stage adds more to the body of the rocket, including the hatch that leads inside, where the player can find a ladder leading up to the cockpit, as well as lockers surrounding the central column. Three levers can be found in this section as well, and it is required to pull them in order to launch. The engine is housed here as well.

Neptune Stage 3.png

The third and final stage represents the main cockpit of the Neptune Rocket. Here the player can access the Time Capsule launcher, main CPU, life support systems, and the command chair which will initiate the launch to escape Planet 4546B.

Lift off

Once the Neptune Escape Rocket has been completed, the player can "say farewell" to their Cuddlefish.[1]

In order for the Neptune Escape Rocket to be able to launch off world there are certain, smaller requirements that have to be met.

Firstly, the player has to activate five out of six Neptune's, various subsystems - three on the lower deck, right after entering the rocket and two out of three on the upper deck, in the cockpit after climbing a ladder. Upon subsystem activation, Neptune's AI will inform the player about it; the ordering doesn't matter. You will also be forced to disable the Quarantine Enforcement platform

Data Bank Entry


This blueprint set was developed at Alterra headquarters specifically to get you off 4546B and back to the nearest phasegate. It takes into account local gravity, astronomical data and available resources, and is piloted by AI. It may be adapted to employ whatever power source is available - but it will require a lot of it.

It consists of five independently constructible elements:

- Launch Platform: Floating platform provides a solid base from which to launch the rocket
- Gantry: Provides structural support
- Stage 1: Primary thrusters for reaching atmosphere escape velocity
- Stage 2: Fuel reserve
- Stage 3: Cockpit

- One-person life support
- Short-range communications
- Adaptable power supply
- Orbital shielding
- Onboard time capsule

Warning: Onboard AI will not launch if local threats are detected.

Warning: The use of alien materials to power the craft may increase its range in unpredictable ways.

  • The Neptune Launch Platform would originally require an Ion Cube Matrix in order to craft the Neptune Fuel Reserve. Version 1.0 removed the Ion Cube Matrix (which was not used in any other crafting recipe) with its place being taken by two Ion Power Cells.
  • The Neptune Escape Rocket was originaly supposed to fly to Earth instead of a phasegate and use "dark matter thrusters" instead of "ion boosters", as evidenced by the original launch sequence dialogue found in the game's files.
  • The Neptune Launch Platform, Neptune Ion Booster's clamps, and Neptune Escape Rocket interior color scheme are not editable; despite any color changes to the Neptune Escape Rocket's exterior.
  • When the player launches the Neptune Escape Rocket, the player can use commands (Freecam) to witness the fact that the Neptune didn't really take off.
